I have Zemax, Code V, FRED ray tracing software.
Why should I be interested in VirtualLab?
VirtualLab Fusion users typically have one or more ray tracing programs, such as Zemax, Code V, FRED or others. For applications with
feature sizes close to, or even less than the wavelength, ray tracing accuracy is reduced. When diffraction, interference, polarization,
wavefront aberrations and temporal and spatial coherence become significant, physical optics modeling is needed.
VirtualLab Fusion does fully vectorial solution of Maxwell's equations. It includes multiple Maxwell solvers and free space propagation methods. Zemax can create a phase function (binary surface), but it cannot design the physical structure for a beam shaper, diffractive lens, metalens, grating or metagrating. VirtualLab can import a Zemax wavefront surface response, and create the physical structure design. Tne Parameter Run in VirtualLab can optimize the structure design, and fabrication files can be exported.

I have Lumerical, RSoft, Optiwave physical optics software.
Why should I be interested in VirtualLab Fusion?
Finite Difference Time Domain (FDTD) software is very useful for modeling nanophotonic devices, but it becomes computationally
intensive as feature sizes increase.
FDTD is not efficient for modeling complete optical systems that require both rigorous analysis and also free space propagation methods. VirtualLab Fusion includes multiple Maxwell solvers and free space propagation methods to model all the microscale and macroscale components in optical systems. The optical system is decomposed into various regions, which are connected throughout the lighpath by nonsequential field tracing to solve specialized Maxwell's equations. The free space propagation methods in VirtualLab Fusion are:Spectrum of Plane Waves, Fresnel operator, Far field operator and Geometrical optics operator. The free space propagation method for each region within the optical path can be automatically determined or manually selected. Automatic propagation selection criteria are chosen to minimize error as well as numerical effort. The recommended propagation method in each region can also be manually overridden. Fourier Transforms switch the modeling between spatial (x) domain and frequency (k) domain to use the most efficient calculation algorithm in each region of the lightpath. Regions with diffractive optical elements, nanostructured components, scatterers, etc., are modeled by Maxwell solvers in the frequency (k) domain for efficient rigorous fast physical optics analysis.

Components in these systems can include refractive lenses, diffractive lenses, hybrid lenses, metalenses, beam shapers, diffusers, microlens arrays, freeform surfaces, high NA optics, grin media, 2D/3D gratings, subwavelength gratings, volume holographic gratings, Bragg gratings, metagratings, ....
